Electric Knife Gate Valve Product Overview
Z971H Electric Knife Gate Valve with multi-turn electric device, so that the valve plate for linear motion up and down, to achieve remote control valve open or closed. Used in chemical, coal, sugar, sewage, paper and other fields, especially for the paper industry in the pipeline for the regulation and throttling use.
Electric Knife Gate Valve Product Features
1, Knife-shaped gate valve in accordance with the different diameter made of dark rod and Ming rod two forms (dark rod DN50 ~ 900mm, Ming rod DN50 ~ 900mm), all round DC channel design does not deposit, The bottom of the blade is machined into a knife-like shape, and the soft material such as fiber, pulp and wood pulp has a cutting function, and has a good opening and closing effect. In the upper end of the board installed with hard polytetrafluoroethylene scraper, to prevent dust, gravel and other scratched material into the packing box, can significantly improve the life of the blade board. Valve plate material selection of stainless steel, fine grinding and polishing treatment can get sealing effect. Compact design, small space, light weight, cheap, easy to install, wear and anti-blocking measures perfect, easy maintenance, easy to use and long life, and can choose any drive device.
2, The valve body, fill the culvert are precision casting, which valve body with the overall casting, the material can be selected according to user needs 304,316,316 L, WCB, 2Cr13, PTFE reinforced PTFE reinforced PTFE material, Corrosion, wear resistance, not sticky residue.
3, The valve plate has five support points, so that the valve plate has a good self-centered. When the valve is in the closed state, and bear the back pressure, the valve plate does not shift.
4, Knife-shaped gate valve can be configured hand wheel, manual zipper, spur gear, bevel gear drive, pneumatic and electric.
5, Knife-shaped gate valve can be made within the V-shaped, triangular, pentagonal channel. V-type gate can be used as a regulator control.
6, Knife-shaped gate valve connection in the form of a clip-on, flange-style, sealed metal-to-metal hard seal, metal to polyurethane, with enhanced Teflon soft seal.
7, For medium: gold ore powder, tailings, pulp, wood pulp, fiber, dust, chemical treatment of sewage, sedimentation tank, ore, slag, slime, asphalt, silo exports, fruit, grain, Plant waste water and so on.
